Polling places in states that span multiple time zones will close
either synchronously or asynchronously.

(Note *S) With synchronized closing,
all the polls close at the same GMT/UTC time. For states with multiple
time zones-- when polls close in the advanced local time zone, they will
close one hour earlier in the lagging local time zone.

(Note *A) With asynchronous closing,
the polls close at different GMT/UTC times in different parts of the
state. Media outlets might decide to declare a winner before
all the polls have closed.

Kentucky General Election: Polls reportedly close asynchronously at 6:00p EST (2300 UTC) / 6:00p CST (0000 UTC). Poll closing time could be rather problematic in KENTUCKY. A large chunk of the state is in Central Time [but the networks consider that "most of the polls have closed" in KENTUCKY by 6 PM Eastern Time and so, if they can, project at the same time they project INDIANA]. Central Time voters in KENTUCKY may note the networks' willingness/eagerness to project a winner as early as 6 PM Eastern Time.

Primary dates marked "presumably" and polling times marked "reportedly" are based on unofficial or estimated data (especially as regards local variations from a jurisdictionwide statutory and/or regulatory standard) and are, thereby, subject to change.
